Description
This application claims the benefit of U.S. Provisional Application No. 61/512,440, filed on Jul. 28, 2011. The entire disclosure of the above application is incorporated herein by reference.
The present disclosure relates to systems and methods for saliva replenishment and control and, more particularly, to mouthpieces and fluid delivery systems.
The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
Saliva production is important to several biological functions including swallowing, digestion, and oral hygiene. For example, enzymes in saliva aid digestion. As another example, saliva hydrates the mouth and throat, aiding swallowing and promoting oral hygiene. Salivary glands may become impaired and/or damaged due to accident, trauma, illness, disease, and/or medical treatments including surgery, medications, radiation therapy, and chemotherapy treatments. In some cases, the accident, trauma, illness, disease, or medical treatment can seriously impair or permanently damage the salivary glands and, as a consequence, render normal salivary production impossible.
As one example, a condition referred to as Xerostomia in the medical community afflicts millions of people worldwide. Xerostomia is used to refer to a condition in which saliva production is impaired or absent. Xerostomia can be caused by various diseases such as Sjögren's syndrome, human immunodeficiency virus (HIV), Alzheimer's disease, diabetes, cystic fibrosis, lupus, and rheumatoid arthritis. As another example, people undergoing cancer treatments such as radiation therapy and chemotherapy to the head and neck often experience a loss in saliva production, and the loss can be permanent. Medications may also diminish saliva production. Saliva production may also diminish as an individual ages and can become problematic at advanced ages.
Several problems can arise in an individual whose saliva production is compromised. Without the ability to produce saliva, an individual may not produce the enzymes necessary to properly digest food. Tooth decay, painful sores in the mouth, problems swallowing, and the inability to eat and speak can arise and can cause other significant health issues. For example, psychological stress and/or other problems can develop. At a minimum, an individual's quality of life can be negatively impacted.
Accordingly, there is a need for devices that can be used to replenish saliva and control saliva production, as well as provide a more convenient way to deliver medications to patients. Several devices have been developed. However, these devices can be improved upon. Specifically, the comfort, versatility, operation, and appearance can be improved upon. Through such improvements, patient compliance with therapies directed to saliva production and other health issues can be improved along with the patient's quality of life. Additionally, such improvements can make certain treatments such as cancer treatments more tolerable and provide for a more stable overall health.
In one form, the present disclosure provides a mouthpiece. The mouthpiece can include a first anchoring member, a second anchoring member, a first tube, and a second tube. The first anchoring member can be adapted to engage a lower dental arch adjacent a first tooth on a first side of a mouth. The first anchoring member can include a first passage extending between a vestibule on the first side of the mouth and a mouth cavity proper. The second anchoring member can be adapted to engage the lower dental arch adjacent a second tooth on a second side of the mouth. The first tube can extend within the mouth cavity proper from the first anchoring member to the second anchoring member adjacent to an inner gum line. The first tube can include a first end fluidly coupled to the first passage, a second end opposite the first end attached to the second anchoring member, and an aperture extending through a wall of the first tube into the mouth cavity proper. The second tube can extend within the vestibule on the first side of the mouth adjacent to an outer gum line. The second tube can include a first end fluidly coupled to the first passage and a second end extending outside of the mouth.
In various features, the second anchoring member can include a second passage extending between the vestibule on the second side of the mouth and the mouth cavity proper. In a related feature, the second end of the first tube can be fluidly coupled to the second passage. In another related feature, the mouthpiece can further include a third tube extending within the vestibule on the second side of the mouth adjacent to the outer gum line. The third tube can include a first end fluidly coupled to the second passage and a second end extending outside of the mouth.
The present disclosure also provides a system that can include the mouthpiece, a portable supply unit, and a stationary supply unit. The portable supply unit can be adapted to be carried by a user. The portable supply unit can include a first fluid system, a first interface module, and a first control module. The first fluid system can be adapted to fluidly couple to the mouthpiece. The first fluid system can supply saliva replenishment fluid to the mouth via the mouthpiece and/or remove fluid from the mouth via the mouthpiece based on first operational settings. The first interface module can receive a first input and can communicate the first operational settings with the stationary supply unit. The first control module can selectively adjust the first operational settings based on the first input and second operational settings communicated by the stationary supply unit. The stationary supply unit can include a second fluid system, a second interface module, and a second control module. The second fluid system can be adapted to fluidly couple to the mouthpiece. The second fluid system can supply saliva replenishment fluid to the mouth via the mouthpiece and/or remove fluid from the mouth via the mouthpiece based on the second operational settings. The second interface module can receive a second input and can communicate the second operational settings with the portable supply unit. The second control module can selectively adjust the second operational settings based on the second input and the first operational settings.
In another form, the present disclosure provides methods related to a mouthpiece and a system according to the present disclosure.
Further areas of applicability of the present disclosure will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.

The present disclosure provides a mouthpiece that can be attached to a lower portion of a mouth and can be used to replenish and/or control saliva in a patient or user. The user can be a male or female and can be an adult or child. The mouthpiece can be used during treatment of temporary conditions such as a temporary loss of swallowing capability due to an accident or trauma, or chronic conditions and diseases such as Xerostomia and cancers affecting salivary function. The mouthpiece can be used to supply and/or remove fluid from the mouth. The mouthpiece is designed so that it can be relatively inconspicuous and minimally intrusive, and can be continuously worn for prolonged periods, for example days and weeks. The mouthpiece is further designed so that it can be used to supply a saliva replenishment fluid in a manner that mimics a normal saliva flow within the mouth. By incorporating such design features, the mouthpiece can be comfortably used without compromising chewing, eating, speaking, and sleeping, and can promote patient compliance with therapies dependent on the use of the mouthpiece.
In various aspects, the mouthpiece can be individually sized and made to fit a particular user. The mouthpiece can have a modular construction that further enables components of the mouthpiece as produced to be altered and custom fit to a particular patient. The modular construction can also enable one or more components of the mouthpiece to be individually replaced without the need for another complete replacement mouthpiece. The components can be individually replaced to maintain a desired sanitary condition of the mouthpiece.
With particular reference to FIGS. 1-3 , environmental views of a lower portion of a mouth 10 illustrate an exemplary mouthpiece 12 according to the present disclosure. The mouth 10 includes lower teeth 20 anchored in a lower jaw bone 22 by gingiva or gum 24. The mouth 10 includes a lower alveolar or dental arch 30 separating a mouth cavity proper 32 and a vestibule 34. The lower dental arch 30 includes alveolar processes 36 that receive roots 38 of the lower teeth 20, the lower teeth 20, and portions of the gum 24 covering the alveolar processes 36 and surrounding the lower teeth 20. The lower teeth 20 can include up to twelve deciduous teeth in a child and up to 16 permanent teeth in an adult. For exemplary purposes, the lower teeth 20 presented include twelve teeth: four incisors 40, two canines 42, 44, four premolars 46, 48, 50, 52, and two molars 54, 56. The lower teeth 20 include lingual surfaces 60 facing the mouth cavity proper 32 and a tongue (not shown), labial or buccal surfaces 62 facing the vestibule 34 and a cheek (not shown) and lips (not shown), and surfaces of contact 64 between adjoining teeth. The lower teeth 20 further include crowns 66 facing upper teeth 70 of an upper jaw bone 72 and defining a lower bite surface or plane 74. Together, the lower teeth 20 and the gum 24 define an inner gum line 80 and an outer gum line 82. Openings of a submandibular duct within the mouth cavity proper 32, which may be referred to as the Wharton's duct, are illustrated by openings 90, 92.
The mouthpiece 12 can include a first anchoring member 100, a second anchoring member 102, a first tubular member 104, and a second tubular member 106. The first and second anchoring members 100 and 102 can attach to opposite sides of the lower dental arch 30 in spaces 110 and 112 adjacent the molars 54 and 56 where second and third molars once resided. In various aspects, the spaces 110 and 112 can be spaces behind rearmost teeth, or in a space where one or more molars once resided such as in the present example. As another example, the spaces 110, 112 can be spaces located in a space between two teeth where one or more teeth once resided. The spaces 110, 112 can be spaces created by extracting one or more of the lower teeth 20 to make room for the first and second anchoring members 100, 102. The spaces 110, 112 can be located in an area of the mouth 10 least affected by the bone loss associated with certain illnesses and treatments. The first and second anchoring members 100 and 102 can be sized to fit within the spaces 110, 112 and not protrude above the bite plane 74. The first and second anchoring members 100 and 102 can be generally solid structures and can have various shapes adapted to fit within the spaces 110 and 112 adjacent to the molars 54 and 56 and adjoining teeth of the upper teeth 70.
With additional reference to FIGS. 4-6 , the first anchoring member 100 can include a crown 120, an anchoring portion 122, and a passage 124. The crown 120 extends from the anchoring portion 122 and can be integral with the anchoring portion 122 as a single piece. The crown 120 can have a generally tapered polyhedral shape as illustrated, or can have a contoured shape resembling a natural tooth that may otherwise reside in the space 110. The crown 120 can include a superior or top surface 130, and an anterior or front surface 132, lateral or side surfaces 134, 136, and a posterior or back surface 138 extending from the top surface 130 to the anchoring portion 122.
The top surface 130 can be adapted and disposed to engage one or more of the upper teeth 70. The top surface 130 can be generally flat as shown and, optionally, can include a portion complementary to adjoining surfaces of the upper teeth 70.
The front surface 132 can be adapted and disposed to engage one or more of the surface of contact 64, the lingual surface 60, and the buccal surface 62 of the molar 56. The front surface 132 can be further disposed to allow one end of the passage 124 to exit the front surface 132 adjacent the lingual surface 60 of the molar 56 and an opposite end of the passage 124 to exit the front surface 132 adjacent the buccal surface 62 of the molar 56. In this way, the front surface 132 can be disposed to allow the first tubular member 104 to extend from the front surface 132 adjacent the lingual surface 60 of the molar 56, and the second tubular member 106 to extend from the front surface adjacent the buccal surface 62 of the molar 56. The front surface 132 can be generally flat as illustrated by the present example and, optionally, can include a portion complementary to the adjoining surface of contact 64 of the molar 56. In this way, the front surface can engage and thereby resist relative movement between the first anchoring member 100 and the molar 56.
The side surfaces 134 and 136 extend from the top surface 130 to the anchoring portion 122 and can be smooth surfaces adapted to engage the tongue and the cheek respectively in a pleasant or comfortable manner. The side surfaces 134 and 136 and the back surface 138 can taper outward from the top surface 130 so that an upper portion of the crown 120 is smaller than a lower portion of the crown 120 and the anchoring portion 122 as illustrated by the present example.
The anchoring portion 122 can include an inferior or gum engaging surface 140 that attaches to the lower dental arch 30 and supports the first anchoring member 100. The gum engaging surface 140 can be generally concave and, optionally, can include portions complementary to portions of the gum 24 defining the space 110. The anchoring portion 122 can engage sides of the lower dental arch 30 facing the mouth cavity proper 32 and the vestibule 34 and, in this way, can resist relative movement between the first anchoring member 100 and the lower dental arch 30 in the medial-lateral direction.
The passage 124 can extend through the first anchoring member 100 and can provide fluid communication between the first tubular member 104 disposed in the mouth cavity proper 32 and the second tubular member 106 disposed in the vestibule 34. The passage 124 can be sized and configured to allow a desired flow rate of fluid between the first and second tubular members 104 and 106. The passage 124 can extend from an aperture 150 disposed in the vestibule 34 to an aperture 152 disposed in the mouth cavity proper 32. The passage 124 can extend through the front surface 132 as illustrated by the present example or, optionally, can extend through one or more of the top surface 130, the side surfaces 134, 136 and the back surface 138.
The passage 124 can include a first leg 154, a second leg 156, and a third leg 158. The first leg 154 can extend through the front surface 132 towards the back surface 138 along an axis 160. The first leg 154 can be adapted to receive an end of the first tubular member 104 in a press-fit arrangement and thereby releasably couple the first anchoring member 100 and the first tubular member 104. The first leg 154 can be sized to receive the first anchoring member 100 at various depths of insertion. The axis 160 can be oriented substantially parallel to the inner gum line 80 or, optionally, disposed on an angle downward towards the openings 90, 92 of the submandibular duct. The second leg 156 can extend through the front surface 142 towards the back surface 138 along an axis 162. The second leg 156 can be adapted to receive an end of the second tubular member 106 in a press-fit and thereby couple the first anchoring member 100 and the second tubular member 106. The second leg 156 can be sized to receive and couple the first tubular member 104 at various depths of insertion. The axis 162 can be oriented substantially parallel to the axis 160 or, optionally, can be oriented at an angle towards a corner of the opening of the mouth 10. The third leg 158 can extend from the first leg 154 to the second leg 156.
With additional reference to FIGS. 7-9 , the second anchoring member 102 can include a crown 170, an anchoring portion 172, and a coupling in the form of a blind bore 174. The crown 170 extends from the anchoring portion 172 and can be integral with the anchoring portion 122 as a single piece as illustrated by the present example. The crown 170 can have a generally tapered polyhedral shape similar to that of the crown 120 of the first anchoring member 100, or can have a contoured shape resembling a natural tooth that once resided in the space 112. The crown 170 can include a superior or top surface 180, and an anterior or front surface 182, lateral or side surfaces 184, 186, and a posterior or back surface 188 extending from the top surface 180 to the anchoring portion 172. The top surface 180 can be adapted and disposed to engage one or more of the upper teeth 70. The top surface 180 can be generally flat as shown and, optionally, can include a portion complementary to adjoining surfaces of the upper teeth 70.
The front surface 182 can be adapted and disposed to engage one or more of the surface of contact 64, the lingual surface 60, and the buccal surface 62 of the molar 54. The front surface 182 can further be disposed to allow the open end of the bore 174 to exit the front surface 182 adjacent the lingual surface 60 of the molar 54. In this way, the front surface 182 can be disposed to allow the first tubular member 104 to extend from the front surface 182 adjacent the lingual surface 60 of the molar 54. The front surface 182 can be generally flat as illustrated. The front surface 182 can include a portion complementary to the adjoining surface of contact 64 of the molar 54 that engages the molar 54 and thereby resists relative movement between the second anchoring member 102 and the molar 54.
The side surfaces 184, 186 can be smooth surfaces adapted to engage the tongue and the cheek, respectively, in a pleasant or comfortable manner. The side surfaces 184, 186 and the back surface 188 can taper outward from the top surface 180 so that an upper portion of the crown 170 is smaller than a lower portion of the crown 170 and the anchoring portion 172 as illustrated by the present example.
The anchoring portion 172 can include an inferior or gum engaging surface 190 that attaches to the lower dental arch 30 and supports the second anchoring member 102. The gum engaging surface 140 can be generally concave and optionally can include portions complementary to portions of the gum 24 defining the space 112. The anchoring portion 172 can engage sides of the lower dental arch 30 facing the mouth cavity proper 32 and the vestibule 34 and, in this way, can resist relative movement between the second anchoring member 102 and the lower dental arch 30 in the medial-lateral direction.
The bore 174 can receive an end of the first tubular member 104 in a press-fit arrangement and, in this way, can couple the first tubular member 104 to the second anchoring member 102. The bore 174 can be sized to receive and couple the first tubular member 104 at various depths of insertion and can seal an end of the first tubular member 104. The bore 174 can extend partially through the second anchoring member 102 along an axis 192. The axis 192 can be oriented substantially parallel to the inner gum line 80 or, optionally, disposed at an angle downward towards the openings 90, 92 of the submandibular duct.
In various aspects, the first and second anchoring members 100 and 102 can be made in a mirror image to that described above. In this way, the mouthpiece 12 may be configured so that the tubular member 104 exits the mouth 10 on the left side of the user.
In various aspects, the first and second anchoring members 100 and 102 can be attached in any suitable manner. For example, a suitable adhesive such as an adhesive that adheres dentures to gum may be used. In various aspects, the first and second anchoring members 100 and 102 can be attached in a semi-permanent manner using a bone fastener. Semi-permanent fastening may be desired for users who expect to use the mouthpiece 12 over a prolonged period and who are unable and/or unwilling to detach and re-attach the mouthpiece 12 as may otherwise be required. In other aspects, the first and second anchoring members 100 and 102 can be positioned against the lower dental arch 30 and attached to an adjoining tooth.
In various aspects, the first and second anchoring members 100 and 102 can be made from any suitable dental material. Suitable dental materials include, but are not limited to, biocompatible polymers such as acrylic materials, and metals such as titanium.
In various aspects, the first and second anchoring members can be off-the-shelf components, semi-custom components, or custom components. As used herein, off-the-shelf components can refer to components made without features based on a particular user. Semi-custom components can refer to components made in advance that include a majority of predetermined features not based on a particular user and at least one feature based on a particular user. Custom components can refer to components specifically made for a particular user. The patient-specific features of a semi-custom component and a custom component can be formed based on a particular user's lower dental arch and surrounding mouth anatomy using various techniques such as dental impressioning techniques.
In one example of off-the-shelf components, the first and second anchoring members 100 and 102 can be selected from a set of components of various sizes made in advance.
In one example of semi-custom components, the crowns 120, 170 of the first and second anchoring members 100 and 102 can be made to predetermined sizes and shapes that are not based on a particular user and the anchoring portions 122, 172 can be made from dental impressions made from a particular user.
In one example of custom components, the first and second anchoring members 100 and 102 can be made entirely from dental impressions made from a particular user. In this way, the crowns 120, 170 can be made to engage and closely match the upper teeth 70. In this way, the first and second anchoring members 100 and 102 can support the upper teeth 70 and can preserve a natural bite plane.
In various aspects, the passage 124 and the bore 174 can be molded in the first and second anchoring members 100 and 102. Alternately, one or more of the legs 154, 156, 158 of the passage 124 and the bore 174 can be formed by drilling into the first and second anchoring members 100 and 102. For example, the first and second legs 154 and 156 can be formed by drilling through the front surface 132. The third leg 158 can be formed by drilling a first passage through the side surface 134 and a second passage through the side surface 136 so that the first and second passages intersect. Plugs can be used to seal the apertures formed in the side surfaces 134, 136 during drilling.
With additional reference to FIG. 10 , the first tubular member 104 can be a length of transparent flexible tubing. The tubing can be round tubing as illustrated by the present example or, alternatively, can have any other suitable cross-section. Transparent tubing can enable the first tubular member 104 to be more inconspicuous and can enable debris and other contaminants that may be present within the tubing to be more easily identified. The first tubular member 104 can be coupled to the first anchoring member 100 via the first leg 154 at a first end 200 and to the second anchoring member 102 via the bore 174 at a second end 202 opposite the first end 200. In various aspects, the first tubular member can be made by bending a length of straight flexible tubing or, optionally, can be made to have a desired pre-formed shape. The first tubular member 104 can extend between the first and second anchoring members 100 and 102 along or just below the inner gum line 80 as illustrated by the present example. For example, the first tubular member 104 can extend below the inner gum line 80 at the front of the mouth cavity proper 32 so that an arched portion 204 is disposed in a natural space between the gum 24 and a bottom of the tongue adjacent to the openings 90, 92 of the submandibular duct.
The first tubular member 104 can include a wall 210 defining a longitudinal passage 212, and one or more apertures extending through the wall 210. For example, two apertures 214, 216 can be provided. The apertures 214 and 216 can be disposed adjacent to, and to face towards, the openings 90 and 92, respectively, of the submandibular duct as illustrated by the present example. In this way, the apertures 214, 216 can supply fluid in the area of the openings 90, 92 and thereby enable the mouthpiece 12 to mimic the normal operation of the salivary gland and create a flow of fluid substantially similar to or mimicking a natural saliva flow. The longitudinal passage 212 and the apertures 214, 216 can be sized so that fluid can pass between the mouth cavity proper 32 and the passage 212. In various aspects, additional apertures can be provided to create the desired flow of fluid. Additional apertures can be provided at various locations to create the desired flow of fluid and/or facilitate the removal of fluid from the mouth. For example, additional apertures can be located adjacent excretory ducts other than the submandibular duct and/or other areas of the mouth cavity proper 32 where saliva tends to pool.
With particular reference again to FIGS. 1-6 , the second tubular member 106 can be a length of transparent flexible tubing. The second tubular member 106 can be coupled to the first anchoring member 100 via the second leg 156 at a first end 220 and to a fluid system (e.g., fluid system 550, 600) located outside the mouth 10 at a second end 222 opposite the first end 220. The second tubular member 106 can include a longitudinal passage 224 sized so that fluid can pass between the mouth cavity proper 32 and the fluid system.
With continued reference to FIGS. 1-10 , exemplary methods of fitting the mouthpiece 12 to a user according to the present disclosure will now be described. According to a first example, a method of fitting the mouthpiece to a user can include at least partially assembling the mouthpiece 12 prior to attaching the first anchoring member 100 and/or the second anchoring member 102 to the gum 24. More specifically, the method can include: (i) coupling the first tubular member 104 to the first anchoring member 100 by inserting the first end 200 within the first leg 154 of the passage 124 to a depth where the first end 200 engages the passage 124 in a press-fit arrangement, (ii) coupling the first tubular member 104 to the second anchoring member 102 by inserting the second end 202 within the bore 174 to a depth where the second end 202 engages the bore 174 in a press-fit arrangement, (iii) attaching at least one of the first anchoring member 100 and the second anchoring member to the lower dental arch 30 after coupling the first tubular member 104 according to (i) and (ii), (iv) attaching a remaining one of the first anchoring member 100 and the second anchoring member 102 to the lower dental arch 30, and (v) attaching the second tubular member 106 to the first anchoring member 100 by inserting the end 220 within the second leg 156 of the passage 124 to a depth where the end 220 engages the passage 124 in a press-fit arrangement. The first method can further include (vi) selecting a user, and (vii) adjusting a fit of the mouthpiece 12 to the user by adjusting the depth of the first tubular member 104 within one of the passage 124 and the bore 174.
According to a second example, a method of fitting the mouthpiece to a user can include coupling the first and second tubular members 104 and 106 to the first and second anchoring members 100 and 102 after attaching the first and second anchoring members 100 and 102 to the gum 24.
With continued reference to FIGS. 1-10 , exemplary methods of using the mouthpiece 12 according to the present disclosure will now be described. According to a first method, the mouthpiece 12 can be coupled to a fluid delivery system and used to supply fluid to the mouth of a user whose saliva production is low. The method can include coupling the mouthpiece 12 to the fluid delivery system and supplying the fluid under pressure to the mouthpiece 12 via the second tubular member 106. Pressurized fluid can be received through the passage 224 and can pass through the passage 124 of the first anchoring member 100 and the passage 212 of the first tubular member 104. The fluid can exit the apertures 214, 216 into the mouth cavity proper 32 near the openings 90, 92 of the submandibular duct where natural saliva is be secreted.
According to a second method, the mouthpiece 12 can be coupled to a fluid removal system and used to remove excess fluid from the mouth of a user whose saliva production is too high or who cannot swallow properly. The method can include coupling the mouthpiece 12 to the fluid removal system and drawing fluid from within the mouth cavity proper 32 through the apertures 214, 216 under vacuum. Fluid drawn through the apertures 214, 216 can pass through the passage 212 of the first tubular member 104, the passage 124 of the first anchoring member 100, and the passage 224 in that order. The fluid can exit the passage 124 and can be collected in the fluid removal system.
In various aspects, the method can further include adjusting a depth of insertion of one or both the ends 200, 202 to adjust a fit of the first tubular member 104 within the mouth cavity proper 32 after attaching the first and second anchoring members 100 and 102. Adjustments can be made to relieve pressure at points of contact between the first tubular member 104 and the gum 24 and thereby provide a comfortable fit. In other aspects, the method can further include replacing the first tubular member 104 and/or the second tubular member 106 without detaching the first and second anchoring members 100 and 102. The first tubular member 104 can be replaced by removing the ends 200, 202 from passage 124, disposing the first tubular member 104, and coupling a replacement part to the first and second anchoring members 100 in a manner similar to that described for the first tubular member 104. The second tubular member 106 can be replaced by removing the first end 200 from the bore 174, disposing the second tubular member 106, and coupling a replacement part to the first anchoring member 100 in a manner similar to that described for the second tubular member 106.
In various aspects, the mouthpiece 12 can be worn while eating and can aid in the chewing and swallowing of food. For example, the mouthpiece 12 can be used to deliver a quantity of saliva replenishment fluid that assists chewing and swallowing. The mouthpiece can enable the saliva replenishment fluid to be delivered at intervals or continuously.
With particular reference to FIG. 11 , an environmental top elevation view illustrates another mouthpiece 300 for use with the mouth 10 according to the present disclosure. The mouthpiece 300 can include a first anchoring member 302, a second anchoring member 304, a first tubular member 306, a second tubular member 308, and a third tubular member 310. The first anchoring member 302, the first tubular member 306, and the second tubular member 308 can be substantially similar to the first anchoring member 100, the first tubular member 104, and the second tubular member 106, respectively.
The second anchoring member 304 can attach to the lower dental arch 30 in the space 112 and can engage the molar 56 in a substantially similar manner as the second anchoring member 102. The second anchoring member 304 can include a passage 312 that can couple to, and that can provide fluid communication between, the first and third tubular members 306 and 310. The passage 312 can extend through the second anchoring member 304, and can couple to the first and third tubular members 306 and 310 in a manner similar to that of the passage 124. In particular, the passage 312 can include a first leg 314 and a second leg 316. The first leg 314 can receive an end 320 of the first tubular member 306 in a press-fit arrangement similar to that created between the first anchoring member 100 and the first tubular member 104. The second leg 316 can receive an end 322 of the third tubular member 310 in a press-fit arrangement similar to that created between the first anchoring member 100 and the second tubular member 106.
The mouthpiece 300 can include the feature that fluid can be supplied to the mouth cavity proper 32 and removed from the mouth cavity proper 32 through separate passages created by the mouthpiece 300. For example, fluid from an external fluid supply unit may be supplied to the mouth cavity proper 32 through the second tubular member 308, the first anchoring member 302, and the first tubular member 306 in that order. Fluid within the mouth cavity proper 32 can be removed to an external fluid recovery unit through the first tubular member 306, the second anchoring member 304, and the third tubular member 310. In various aspects, the third tubular member 310 can be sized and configured to allow a desired flow rate of the fluid to be removed. For example, the third tubular member 310 can have a larger passage than the first and second tubular members 306 and 308 where the fluid to be removed has a viscosity that is greater than a viscosity of the fluids to be delivered.
With particular reference to FIG. 12 , an environmental top elevation view of a mouth 10′ illustrates another mouthpiece 400 according to the present disclosure. The mouth 10′ is substantially similar to the mouth 10, except that the mouth 10′ includes two additional molars 402, 404. The mouthpiece 400 can include a tube assembly 410 and anchoring members 412, 414, 416, 418. The tube assembly 410 can be adapted to transfer fluid between a first location in the mouth cavity proper 32 and a second location outside of the mouth 10′. For example, the tube assembly 410 can supply fluid from a fluid supply unit located outside the mouth 10′ to the mouth cavity proper 32. As another example, the tube assembly 410 can be used to remove excess fluid within the mouth cavity proper to a fluid recovery unit located outside the mouth 10′.
The tube assembly 402 can include a first tubular member 420, a second tubular member 422, a flexible first tube 424, and a flexible second tube 426. The first tubular member 420 can be adapted to provide fluid communication between the first and second tubes 424 and 426 and to pass through a space 430 adjacent a rearmost tooth. The first tubular member 420 can be further adapted to support the first and second tubes 424 and 426. According to the present example, the first tubular member 420 can be a rigid U-shaped tube that extends from the vestibule 34, around the molar 404 through the space 430, and to the mouth cavity proper 32.
The first tubular member 420 can include a first opening 432 at a first end adapted to receive an end 434 of the first tube 424 in a press-fit arrangement. The first tubular member 420 can include a second opening 436 at a second end opposite the first end that receives an end 438 of the second tube 424 in a press-fit arrangement. The first tubular member 420 can be attached to the mouth 10′ in any suitable manner. For example, the first tubular member 420 can be attached to one or more of the lower teeth 20. According to the present example, the first tubular member 420 can attach to the molars 56 and 404 via the anchoring members 412 and 414, respectively. The first tubular member 420 can cooperate with the anchoring members 412, 414 to support the ends 434 and 438 of the first and second tubes 424 and 426 at a desired orientation or angle.
The second tubular member 422 can be adapted to seal an end 440 of the second tube 426 and can be further adapted to support the end 440 within the mouth 10′. The second tubular member 422 can be an elongated rigid cylindrical cap that includes a first open end 442, a second closed end 444, and a longitudinal passage 446 at a desired orientation or angle. The longitudinal passage 446 can extend through the open end 442 towards the closed end 444 and can be adapted to receive the end 440 of the second tube 426 in a press-fit arrangement. The second tubular member 422 can be attached to the mouth 10′ in any suitable manner. For example, the second tubular member 422 can be attached to one or more teeth in a manner similar to that of the first tubular member 420. According to the present example, the second tubular member 422 can attach to the molars 54 and 402 via the anchoring members 416 and 418, respectively. The second tubular member 422 can cooperate with the anchoring members 416 and 418 to support the end 440 of the second tube 426 within the mouth 10′ at a desired orientation or angle with respect to the openings 90, 92 of the submandibular duct.
The first tube 424 can be a length of flexible tubing adapted to couple to the first tubular member 420 and to transport fluid between the first tubular member and a desired location outside of the mouth 10′. The first tube 424 can extend through the vestibule 34 and can be sized to provide a desired fluid flow.
The second tube 426 can be a length of transparent flexible tubing adapted to couple to the first and second tubular members 420 and 422. The second tube 426 can be further adapted to extend along the inner gum line 80 at a desired orientation with respect to the tongue and the openings 90, 92 of the submandibular duct and to retain a desired shape. The second tube 426 can be substantially similar to the first tubular member 104 and can include apertures 450 and 452 disposed along the length so as to be located near the openings 90, 92 of the submandibular duct. In this way, the apertures 450, 452 can direct fluid towards an area where saliva excreted through the openings 90, 92 would normally collect.
The anchoring members 412 and 414 can be adapted to attach the first tubular member 420 to the molars 56 and 404, respectively. The anchoring members 416 and 418 can be adapted to attach the second tubular member 422 to the molars 54, 402. In various aspects, the anchoring members 412, 414 can have a substantially similar configuration. Accordingly, the anchoring member 412 will be described in further detail with the understanding that the description can apply equally to the anchoring member 414.
With particular reference to FIG. 13 , a perspective view illustrates an exemplary configuration of the anchoring member 412. The anchoring member 412 can include a cap 460 and a clip member 462. The cap 460 can be adapted to engage the crown 66 of the molar 56 in a close fit and to support the clip member 462 on the molar 56. The cap 460 can be formed of a thin material, such as a metal, and can have a contour complementary to the crown 66 of the molar 56. The clip member 462 can be attached to the cap 460 and can be adapted to releasably retain the tube assembly 410 and, more particularly, the first tubular member 420. The clip member 462 can include U-shaped clips 464 and 466 having inwardly turned ends 470 and 472, respectively, which can releasably retain respective portions of the first tubular member 420 in a snap-fit arrangement.
The anchoring members 416, 418 can have a substantially similar configuration and the configuration can be similar to that of the anchoring members 412, 414. For example, the anchoring members 416, 418 can include a cap and a clip member substantially similar to the cap 460 and the clip member 462 described above, except that the clip member can include a single clip that releasably retains the second tubular member 422.
In various aspects, the mouthpiece 400 can be configured with an additional tube similar to the mouthpiece 300. For example, the mouthpiece 400 can include a second tubular member substantially similar to the first tubular member that attaches to the molars 54, 402 via anchoring members similar to the anchoring members 412, 414. The second tube can be coupled to an end of the second tubular member disposed in the mouth cavity proper 32 and a third tube can be coupled to an opposite end of the second tubular member disposed in the vestibule 34. The third tube can extend from the second tubular member to a location outside of the mouth.
With particular reference to FIG. 14 , a functional block diagram illustrates an exemplary system 500 according to the present disclosure. The system 500 can include a mouthpiece 502, fluid couplings 504, 506, a portable supply unit 508, and a stationary supply unit 510. The system 500 can further include a moisture sensor 511 that senses a moisture content of the mouth and outputs a signal indicative of the moisture content sensed. In various aspects, the moisture sensor 511 can be attached to the mouthpiece 502 and can be formed integral with a component of the mouthpiece 502 as a single part. Alternatively, the moisture sensor 511 can be attached to a separate location within the mouth.
The mouthpiece 502 can be a mouthpiece according to the present disclosure such as one of the mouthpieces 12, 300, 400. For exemplary purposes, the mouthpiece 502 presented can be substantially similar to the mouthpiece 300 and can include a first anchoring member 512, a second anchoring member 514, a first tubular member 516, a second tubular member 518, and a third tubular member 520. The first anchoring member 512, the second anchoring member 514, the first tubular member 516, the second tubular member 518, and the third tubular member 520 can be substantially similar to the first anchoring member 302, the second anchoring member 304, the first tubular member 306, the second tubular member 308, and the third tubular member 310, respectively.
The fluid coupling 504 can couple the second tubular member 518 to the portable supply unit 508 or the stationary supply unit 510 as desired.
